Central heating programmer cable 3 and earth

Hi,
Hope you're all doing well. I have a customer who needs a 5 core cable to the boiler from the wiring centre. At the moment the feed is coming from a 13a socket in the upstairs cupboard through the programmer into the wiring centre and then 3 and earth under bathroom floor and into the kitchen. In order to get the 4th cable they were using the earth. The plumber has obviously put this back to its original purpose but now there's 1 cable too few - line, neutral, earth, call for heat and call for hot water.
Under the boiler is a fused spur for the cooker hood. Is it possible to use this as the feed for the boiler allowing the line or neutral cable to be used for the call for heat?

I hope this makes sense. Sorry I should have taken pictures but thought of posting here with this "fix" after I left!

Cheers

Paul
 
If the boiler needs only sw live,N and earth and the programmer is a two-channel stand-alone programmer then could have the existing supply have the programmer there and put an isolator before the boiler.
